This invention relates to improvements in wood shapers and is directedto improvements in the efiiciency in operation thereof.

A primary object of the invention is toprovide novel means for mountingthe cutter in order to eliminate any possible displacement thereof andto insure direct action by the motor-at all times.

Another importantobject ofthe invention is to provide means to retainthe cutter elementdirectly on the drive means itself and'thus avoid theinconvenience and expense of Separatelyoperating connections generallyinuse today with the accompanying loss in motion when the. operation ofthe device is begun, aswellas the additional elements used beingsubjecttornechpanicaljailure and replacement.

And another important object of the invention is to eliminate theusual.type -,of end-.thrust provided for motors innse today. and bythe-use.

of a rotatable ball upon which the-..mo.tor-;spindle.

rests, attaining. the identical result obtained in the usual and moreexpensive motors now available.

Still another object of the invention is to provide means foradjustingthe height of j the work table by simple rotative movement of ahand wheel in connection withthesaidwork table.

With these features in view, the invention-con. sists of certainfeatures of novelty in the. construction. combination and. arrangementofparts by-whiohsaid features andcei others, hereinaiter appearing, areeffected eall aS:-f.ully.-;described with reference,- to the,accompanying drawings and more particularly ;pointed .outgin theappended claim.

In the drawings:

Figure 6 is an enlarged vertical sectional view of the adjusting means;

Figure 7 is an enlarged view of the cutter and 2 theamounting meanstherefor illustrated in Figure-1 and Figure-B-isan end view of thecutter element.

:Referring to the figures, the wood shaper of the invention is indicatedgenerally at it and includes a base H.- upon which an adjustable tablesupport M is securedon a base plate retained on-base 1-2 by suitablemeans such as bolts t8; A-work table '20 is adjustably retained inposition by a support plate 22 secured thereto by retaininggbolts 24 orthe like. A cutter 28 is mounted and retained above table 26 inoperative POSiti-OflyfiS willsoon be described.

MotqrflB-is retained on an upwardly tapering support 38 suitably'mountedon base l2 and is conneotedbywires 3-21to an actuating switch 3% and asource of current supply, not shown, in the; usual manner, thisformingno part of the invention. fMotor ZBincludes the usual motorspindle-"136' extending axially therethrough and retained in an upperbearing. or bushing 38 secured'inadjustable supportmeans i l at the up.-per end thereof and in a similar bushing is retainedfinacounterboredportion 44. of motorsupport -3fli It is to be noted at this point thatthe lower end of spin-dle; 36 does not .contain the usual endi thrustbearing provided in motors in use todamjbut instead: terminates in astraight shaft haaex ends nt a bea 6 w h n a ces Mijinthe supporttflandseatsupona spindle ball Qtjretained on the base of" counterbore A l"and with nthebear ns .5 t ta th eo T us. it is readily apparent that asimplified type of motorhas been provigledand onewhich attains theidenticalre lllts of other motors now in use withjtheelirnination.of.cost in the manufacture thereof. Theupperportionof spindle iijfiextending beyonjdjmotor 23 includes a sleeve its, spin-ale 3 fif,' an d,sleeve AB extending through suitable apertures'SU' and 52in supportplate22 and work table 20, respectively. Sleeve i8 terminates at shortdistance below the upper extremity of spindle 36 and forms an annularseating shoulder 54. Spindle 36 terminates in a threaded section 55where it projects beyond sleeve 48 in order to receive cutter heads 25and locking means therefor thereon.

Referring to Figures 1 and 7, one form of cuter 26 is illustrated andincludes an apertured annular ring 58 rotatably retained on spindle end56 and seating on shoulder 54 of sleeve 48. Ring 58 includes a pair ofoppositely disposed cutters 60 includingcutting edges 62 in a mannerwell known in the art. A cutter looking or retaining means 64 is axiallybored throughout the length thereof and is rotatably received on spindleend 56 to seat on the upper extremity of ring 50 and thereby press itinto non-movable position on shoulder 54 of sleeve 48, lock 64 beingsecured to spindle 36 by suitable set screw means 66. A modification inthe construction of the spindle and cutter is illustrated in Figures 2and 5, spindle 35 including a transverse slot 68 and cutter 26containing a depending transverse flange on the lower extremity thereofto seat in keyway 68, thereby insuring additionally the non-sliprelation thereof. Cutter lock 12 is similar in construction to lock 64,but different therefrom in that the axial bore therein terminates in thehead portion thereof and does not extend entirely therethrough. Setscrew 86 serves to retain lock '12 on spindle head 56.

The adjustable support includes a depending,

4 belt connections is eliminated and cutter 26 is directly driven frommotor 28. Spindle 36 rotates freely on ball 46 and thereby eliminatesthe necessity for supplying end thrust bearings normally employed. Whenit is desired to adjust table 20, hand wheel I00 is rotated, therebymoving support in avertical direction until the desired height has beenattained.

It is to be understood that the invention above described is not limitedto the exact arrangement and combination of parts as described in thespecification, nor is the invention limited to the exact details ofconstruction as illustrated in the accompanying. drawings.

Having described the invention, what is claimed as new is:

- A Wood Shaper comprising a base, a pair of uprights rising "from thebase and having upper transverse frame 14 secured integrally with the wJ lower portion of plate '22 and containing depending legs 16, legs 16including lateralaper tured guide or slideway sleeves l8 and a medial,laterally and downwardly bar 80 extending therefrom. Lateral braces 82are provided for support member M, as is clearly seen in Figure 1. Guidesleeves I8 receive therethrough vertically extending support rods 90suitably journaled at 86 at the lower extremity thereof, their journals8'6 being welded or otherwise mounted on base plate [6. tremities ofsupport rods 90 and serve as a stop means for the vertical adjustment oftable support 22, bearings 88 being held in operative position by meansof vertical support members I4 mounted on base plate I6. The bar 80 ter-0 minates in a lateral apertured bearing 92, threaded internally toreceive therein a threaded rod 94 mounted in counterbore 96 (Figure 6)and suitably welded thereto at 98 in hand wheel I00.

Hand wheel I00 includes a lower, axially counterbored base I 02, boreI04 retaining a vertical stud or key I06 extending from base plate I6and thereby retaining wheel I00 in operative position. Thus, by rotatinghand wheel I00, threaded rod 94 rotates to vertically adjust supportplate 22, and as a consequence work table 20, this being possible by theengagement of slideway sleeves 18 with support rods 90. Bearings 88 stopthe vertical movement of support 14 to prevent disengagement thereoffrom the retaining means. Motor 28 is also retained in position by across member 90 whose ends receive bolts I08 that are threaded inapertures the rear of support I4. 2

In use, the desired cutter head 26 is seated on the extending extremity56 of spindle 36 and is retained thereon by suitable locks 64 or 12.Since spindle 36 extends through motor 28 and retains cutter headthereon, the necessity for providing auxiliary equipment such as pulleyand Bearings 88 engage the upper exand lower lateral projections, eachof said projections having a vertical bore therein with the bores in theupper projections being in registry with the bores in the lowerprojections, a pair of guide bars extending through the bores in saidprojections and paralleling said uprights, a horizontal table, asubstantially U-shaped frame depending from the table and including apair of vertical legs, vertical guide sleeves carried by said legs andslidable on said bars between said upper and lower projections, ahorizontal crossmember mounted on and extending between said uprights, amotor supported on said base and also supported by said cross-member,said motor including a vertical drive shaft, said table having anopening receiving said shaft, a vertical stud rising from the base, ahand wheel having a hub, said hub having a recess receiving said stud,an arm inclining downwardly from the frame and having a horizontalextension at its lower end overlying the hand wheel, said extensionhaving a threaded aperture therein, and a threaded rod fixed to saidwheel and threaded in said aperture.
